Measurement of the radiation environment from LEO to GTO using the CREAM and CREDO experiments

The Cosmic Radiation Environment and Dosimetry experiment (CREDO) on STRV-1a is monitoring the radiation environment in geostationary transfer orbit (GTO) and in conjunction with similar detectors in low earth orbit (LEO) affords coverage of the whole magnetosphere. Results are showing the time variability in the environment and are testing the standard models.
